Operating manual
TR 101
Application
Thermostats of the TR series are temperature controllers. The thermostat switches
operate when the set limiting value is exceeded.
TR thermostats and Pt 100 temperature sensors are a reliable monitoring system.
Possible damage by excess temperature in machines and plants are positively avoided.
ZIEHL thermostats of the TR series are electronic two- position controllers. Modern
circuitry, well- proved components as well as function and routine tests ensure high
repeat accuracy and a long service life.
Function
As standard, the TR 101 thermostats operate according to the closed- circuit current
principle. If a temperature sensor is connected, the installed relay picks up.
The relays always switch off in the case of a sensor breakdown.
If the measured temperature has additionally to be displayedor transfered to an
overriding computer system, the thermostat TR 101 supply the corresponding analog
output signal 0 - 20 mA ( 4 - 20 mA , 0 - 10 V ).
The TR 101 unit can thus be used as thermostat and measuring transmitter at the same
time. Panel instruments of the ZIEHL MINIPAN series are especially suitable for
temperature display.
